Description of PR

Summary:
DHCPv6 infrastructure and automatic test.

Type of change

  • Bug fix
  • Testbed and Framework(new/improvement)
  • Test case(new/improvement)

Approach

What is the motivation for this PR?

Add DHCPv6 automatic test infrastructure and PTF test.

How did you do it?

Enhance the minigraph_facts.py and minigraph_dpg.j2 to support DHCPv6 instances.
Add DHCPv6 servers to lab.yml file.
This will deploy on a DUT DHCPv6 servers on regression run.
Develop a test with 3 test cases:

  • test_dhcp_relay_default
  • test_dhcp_relay_after_link_flap
  • test_dhcp_relay_start_with_uplinks_down

Develop a PTF runner test to simulate the traffic according to the test case from sonic-mgmt.

How did you verify/test it?

Supported testbed topology if it's a new test case?

… dhcpv6 relay test

Add ansible group variable "dhcpv6_servers" for the new dhcpv6 relay test

PR sonic-net#3767 introduced dhcpv6 relay test script
that needs variable "dhcpv6_servers" predefined in ansible group vars visible to DUTs.

This PR is to define the "dhcpv6_server" group variable in 'ansible/group_vars/str/str.yml'
and 'ansible/group_vars/str2/str2.yml' which are used by our starlab DUTs.

This test depends on PR: [dhcp_relay] DHCP relay support for IPv6 sonic-buildimage#7772

Supported testbed topology if it's a new test case?
